|Diagnosis||Diagnosis. A large Gehyra species (to 77.1 mm SVL) differing from all other Gehyra species outside the G. koira complex as per the diagnosis above. Differs from other members of the G. koira complex in the combination of: moderate size within complex (adult SVL up to 77.1 mm, mean 69.4 mm); head relatively wide (HW/SVL 0.19–0.21); nostrils usually separated by more than 2 internasal scales (87.5%), rarely 2 (14.3%); second chin shields approximately two-thirds the length of first chin shields (mean|
ratio 0.66, range 0.53–0.79); first chin shield pair not bordered posteriorly by a single enlarged medial gular scale, or if present, median scale is not the largest in first row of gulars; pores in males relatively few (9–14); and adults with tan to brownish dorsum and tails, and with a dorsal pattern including distinct light tan ocelli or blotches (as opposed to transverse light bands).
Further diagnosed from other species within the G. koira complex genetically by six unique amino acids in the ND2 locus (Table 1).
Gehyra calcitectus sp. nov. differs from two members of G. koira complex with which its distribution abuts or overlaps as follows: from G. koira in having a dorsal pattern including light pale tan ocelli or blotches (vs. transverse bars), lower number of pre-cloacal pores (9–14 vs. 12–23), and for eastern populations in having dark-brown dorsal spots across the head and often torso (vs. absent); and from G. ipsa in its smaller size (mean and maximum adult SVL respectively 69.4 mm and 77.1 mm vs. 84.9 mm and 94.9 mm), absence of an enlarged scale behind the first pair of chin shields (vs. presence) and pale dorsal pattern elements consisting of ocelli or pale blotches (vs. pale transverse bands). From the geographically disjunct G. lapistola sp. nov., it differs in having a dorsal pattern comprising pale ocelli or blotches (vs. at most pale transverse bands).
The distribution of G. calcitectus sp. nov. is largely geographically disjunct from most members of the G. koira complex, including G. ipsa, G. lapistola sp. nov. and G. chimera sp. nov., and accurate locality data may permit identification of morphologically similar specimens.
|Etymology||The species epithet is formed from the Latin words calcis (limestone) and tectus (hidden, hideaway), as in ‘limestone-hidden’ or ‘limestone hideaway’, in reference to the species occurrence in and apparent preference for limestone habitats of the Kimberley limestone ranges. Used as a noun in apposition.|
